OUTLET FOR J'ACKETED VESSELS.

Application filed December 30, 1920.

To aZZ. whom it may concern Be it known that I, EDGAR B. NICHOLS, a citizen of the United States residing at Rochester, in the county of Monroe and State of New York, have invented new and useful Improvements in Outlets for J acketed. Vessels, of which the following is a specification.

This invention relates to outlets for jacketed vessels and the principal object of the invention is to provide a connection between an outlet that extends through the side or bottom of a vessel and the jacket thereof, whereby independent expansion and contraction may occur without undue strain on either member. Another object of the invention is to so construct the outlet and connection that the latter may be readily removed when itrbecomes necessary to detach the jacket from the vessel, and so that the connection may be cheaply and easily replaced.

In the drawings:

Figure 1 is an exterior elevation of a jacketed vessel embodying this invention;

Fig. 2 is a fragmentary vertical section through a side outlet;

Fig. 3 is a perspective view of the flexible connector; and

Fig. 4 is a transverse section of the flexible connector when partially completed, in process of manufacture.

In jacketed vessels or kettles of various types it frequently becomes necessary to provide an outlet extending from the side of the vessel through the side of the jacket,

which usually results in a more or less cumbersome and awkward construction, tending to cause leakage, and also setting up irregular stresses in the vessel structure.

The present invention is intended to overcome the foregoing objections and is particularly applicable to kettles or vessels which are lined throughout their interior, including all outlets, with a protective coating of enamel. If this latter is composed of glass particular precautions must be taken to provide a connection between the outlet and the jacket which will obviate the irregulas stresses before mentioned, and also which will permit of readily attaching the jacket and its fixtures after the enamel has been applied to the inner vessel.-

In the construction illustrated herewith the inner Vessel 1 and the jacket 2 are cylin- Specification of Letters Patent.

drical in form and are provided with dished bottoms 3 and 4 respectively. A dished top head 5 is welded to the opposite end of the jacket 2 and the top edge of the inner vessel is also welded to this head at 5*. I In the present structure a bottom'outlet 6 and a side outlet 7 are shown, each of these being of the threaded nipple type. In enameled vessel construction the bottom and. side of the inner shell may be perforated and swedged outwardly as at.8 and the nipple is welded to the swedged out portion. When the enamel is applied to the vessel the interior of the nipple is alsocoated.

In order to provide for the flexible connection which is the subject of this application, an annular. flange 9 is fixed to the nipple 7 preferably by welding. If it is attached by the latter method it must be done before the vessel is enameled, it being understood that the high temperature of welding would be injurious to the glass lining or other protective coating.

The flexible connector which serves to close the annular opening between the flange 9 and the opening in the jacket through which the outlet 7 projects comprises an annular trough-shaped piece of comparatively thin metal that may be formed in any suitable manner and may be inserted within the jacket, its inner edge being attached to the periphery of the flange 9,, and its outer edge to the jacket 2, preferably by autogenous welding.

This connector 10 may be spun from sheet metal, drawn in dies, or formed in various other ways. A preferred method of form ing this part consists in flattening a length of thin tubing 11 so that its cross-section is approximately the proportions indicated at 12 in Fig. 4:. This tubing is then rolled into a ring and its ends welded together. About one third of the ring is then cut oil' as indicated by the broken line AA and the remaining portion is then spread so that a cross-section of any portion will be approximately V-shaped. The piece will then have the appearance shown in Fig. 3. In this form it is obvious that the part 10 will yield to stresses applied from the top, bottom or sides in any direction approximately parallel to the jacket.

The advantage of the construction herein illustrated is apparent when it becomes necessary to provide a comparatively long nip:

ple or outlet through the side of a jacketed vessel. In this case, in order to placethe jacket in position, the latter must be moved over close to the side of the vessel opposite thefoutlet and therefore, if a bottom outlet is provided in the center that is also longer than the jacket space, said bottom outlet will be eccentric to the opening provided for it in the jacket head. permit the bottom nipple to pass through the jacket so that the Side outlet can be brought into horizontal alinement withthe opening in the side of the jacket and passed through the latter, it is necessary to provide a comparatively large opening in the bottom jackethead. Heretofore it has been custom ary to close the space left between the outlet nipple and the jacket opening by means of a flexible diaphragm bolted or screwed in the nipple and the jacket, or other more cumbersome and expensive constructions.

The present inventionovercomes the foregoing objection by providinga single piece of metal so formed that it is capable ofcompression and expansion and which may be cheaply made, and applied with a minimum amount of labor. i V It has been found in practice that connec tors made as herein described, can be quickly removed by cutting them away with an acet -lene torch, and because they are cheap to 'manufacture no pains need be taken to salvage the old part, but the necessary care may be exercised to prevent damage to the jacket or the flange ,9 on the outlet. 1

Therefore, in order to.

substantially This invention is not limited to the specific form shown but maybe modified in various ways to serve the same purpose as embraced in the scope of the following claims.

I claim 1. An outlet for acketed vessels comprising a nipple extending from the vessel; an annular collar on said nipple, and a ring of U-shaped cross-Section, the inner edge of the ring being weldedcto said collarand the outer edge of the ring being Welded to the acket of the vessel.

2. An outletfor j acketedvessels comprising a nippleexten'ding from the vessel and provided with an annular collar, the jacket of the vessel having an opening concentric with said collar and a ring of substantially Ll-shaped cross-section having its inner periphery welded to the annular collar and its outer periphery fitted within the opening in the jacket-and welded to thelatter.

3. An outlet for jacketed vessels comprising a nipple extendingfrom the vessel and having an annular collar substantially in the plane of the jacket, the latter being provided with an opening larger than the said collar; and an annular piece of comparatively thin and flexible metal 'of trough-shaped cross section, said piece having its inner edge fixed to therannulai'collar and its outer edge fixed to the periphery f the opening in the jacket,

preferably by welding.
